Remove and Replace an iSCSI Bridge

The Scalar i3 iSCSI bridge offers an integrated, scalable solution enabling you to connect SAS drives to Ethernet networks using the iSCSI protocol. iSCSI allows SAS to be used where SAS cable distances previously prevented the uses of SAS tape drives.

The iSCSI bridge available in two (2) configuration options; two (2) 10 GbE SFP+ Optical or two (2) 10 GbE RJ45 SFP Copper ports.

Power Supply Requires 440W power supply to be installed. 315W power supply is not supported.

Item Name Description

1

Power Supply

LED indicates the following:

  • Green LED - Indicates power is applied to the iSCSI bridge.
2 Ready Alert

Status of iSCSI bridge.

LED indicates the following:

  • Green LED - Indicates initialization completed and is ready for use.

  • Yellow LED - Indicates an alert or fault condition in the unit.
3 Ethernet Ports

Connects to Ethernet networks. Two different options:

  • Two 10 GbE SFP+ Optical

  • Two 10 GbE RJ45 SFP Copper ports

LEDs indicate the following:

4 Ethernet Management Port

One 1GbE RJ45 port.

LEDs indicate the following:

  • Link LED (left) - Solid green when linked at 1Gbps, off when linked at 100 Mbps or not linked.

  • Activity LED (right) - Blinks green to indicate port activity.
5 SAS Port

Provides tape drive connectivity. 12Gb Mini-SAS HD SFF 8644 port on bridge; negotiates to 6Gb as needed.

LED indicate the following:

  • A blinking LED indicates SAS activity.

iSCSI Bridge Replacement

  1. Save the iSCSI Bridge Configuration.

    Use the DumpConfiguration CLI command to save a copy of the current iSCSI configuration. Refer to the Scalar iSCSI Bridge Installation and Configuration Guide.

  2. Disconnect the Ethernet cables and SAS cable from the iSCSI bridge.

  3. Loosen the thumbscrew and remove the iSCSI bridge from the library.

    Caution: Before removing the iSCSI bridge, attach an ESD strap to your wrist and to an unpainted surface on the library.

  4. Slide the new iSCSI bridge in until you feel the connector slip into the library connector.
  5. Tighten the iSCSI thumbscrew.

  6. Reconnect the cables to the iSCSI bridge exactly as they were before.

  7. Restore the iSCIS bridge configuration. Refer to the Scalar iSCSI Bridge Installation and Configuration Guide.
